Hi Si and all (1 x Enter)Bernd is not alone. It has been doing it to me using Chrome for months.

I have to use (2x Enter) to get a line separation. (3 by Enter)

goes to here
The only way I can add a link it to manually type in the code [ url] [ /url] (without the spaces). For photos I have to use the code [ img] [ /img]
This ought to look real funny when it appears as a message.

If you look at most of my recent messages you will see that they have been edited by me to get the line spacing right after being posted.
